Vanilla Ice Cream From John's Recipe Collection Yield: 2/3 cup * 1 egg yolk * 1/4 cup whole milk * 1/4 cup heavy cream * 2 tbsp. sugar * 9/16 tsp. vanilla Whip the egg yolks while adding the sugar slowly. Continue whipping until it's smooth. Add the milk and mix thoroughly. Cook the custard over medium heat, stirring constantly with a wooden spoon, until it is thick enough to coat the back of the spoon. This should happen at about 165 degrees F - 170 degrees F. If the custard starts to fill with lots of tiny flecks, you've cooked it too far - stop! Remove the custard from the heat and cool to refrigerator temperature. Add the cream and vanilla. Mix well. Freeze using your method of choice.
